They could be referring to "cubic inch displacement." This is the total volume that all of the pistons in your engine displace when each piston has moved from the bottom of it's stroke to the top of it's stroke once. Usually it is referred to as cid. A typical example would be a Chevy 305 V8 where the 305 is the cid. Most foreign cars use cubic liters rather than cid. A typical example would be a 2.4L engine which is 2.4 cubic liters displacement.
